Description

Technical Field

[0001] This invention relates to the fields of building engineering doors and windows, furniture and equipment, and more specifically to a multifunctional movable partition screen. Background Technology

[0002] Partition screens are widely used in applications requiring flexible space configuration, especially movable partition screens. To ensure the privacy of each partitioned space, the requirements for screens are becoming increasingly stringent. For example, the vertical gaps between screens should be minimized, sound insulation should be excellent, and movable partition screens should be easy to move. Many existing movable partition screens are designed with sealing strips or adjustable telescopic panels at the top, bottom, left, and right to achieve the desired separation effect. The sealing is achieved by manually adjusting the extension or retraction of these panels to suit different application scenarios. Each of these screens requires a telescopic plate operator and a telescopic transmission assembly, which increases costs. The taller the screen, the longer the telescopic transmission mechanism assembly must be, further increasing costs and the weight of the screen, making it more difficult to push. The pushing and / or pulling force of the telescopic plate varies depending on the force applied by the operator, making it impossible to set a suitable and stable pushing and / or pulling force according to the required force. Therefore, the sealing effect of the acoustic partition when the sealing strip on the telescopic plate presses against the floor (or rails) is not stable. The higher the screen, the longer the telescopic transmission mechanism components, resulting in higher costs and increased screen weight, making it more difficult to move. Each screen requires repeated use of a stirring handle (or tool) to operate the telescopic panel, increasing time and efficiency with more screens. The space occupied by the telescopic operators and transmission components cannot be filled with sound insulation material, reducing soundproofing effectiveness. The significant space occupied by these components, especially in glass screen applications, greatly reduces the visible window area, severely impacting appearance and lighting. Furthermore, the telescopic operators must be used with a stirring handle (or tool), which is usually stored separately and retrieved only when needed. Previously, situations frequently arose where others couldn't find the handle and therefore couldn't operate the screen. In the event of a fire or natural disaster, additional time must be spent searching for the handle before moving the screen, delaying evacuation.

[0003] To address the difficulties of manual operation, motorized screens were proposed. These screens use motors to drive the extension and retraction of the panels and sealing strips, replacing manual operation. However, since electricity is required, a reliable power supply system is essential to ensure power safety. Traditionally, power is connected to walls or pillars via wires or contact electrodes. However, in many applications, there is no space or suitable location for pillars, or no usable walls nearby, making power connection difficult. Furthermore, using a single power circuit means that the drive motor will malfunction in the event of a circuit failure or power outage, limiting practical applications and increasing the risk of accidents. Summary of the Invention

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] To address the shortcomings of existing manual and conventional electric partition screens, this invention proposes targeted improvements, implementing a multi-power supply scheme that provides top power via a rail and also side power. A compact, electrically retractable structure achieves automatic sealing in all directions. This structure is widely applicable to partitions made of various materials, including wood, metal, and glass, or combinations thereof. Furthermore, depending on the application scenario or product function, various electronic and electrical devices or equipment with different functions can be freely and selectively installed on the movable partition screen, either simultaneously or selectively. For example, various electronic and electrical devices, components, or equipment with features such as electro-optical glass optical visibility, optical shielding, LCD digital screen display, LED lighting display, sound playback system, sound isolation, and audio-visual system can be installed and attached to the movable partition screen, allowing for arbitrary movement. Therefore, this technical solution can realize multi-functional automatic or semi-automatic acoustic movable partition screens. The air vent can be configured to simultaneously or selectively possess: electro-optical glass optical transparency and optical shielding functions; digital screen display functions; sound playback device functions; video playback device functions; LED screen sound and light device functions; movable aquarium functions; negative ion generator functions; ultraviolet sterilizer functions; air purifier functions; flexible video playback screen functions; and various other electronic and electrical devices or equipment (including but not limited to the functional applications of the above-mentioned devices or components). Various multifunctional applications can be combined and moved or fixed arbitrarily with the glass movable partition screen to complete the partition or display of its application functions.

[0043] The multifunctional movable partition screen is a system solution that has been improved in various dimensions, including the following aspects: power supply, electric control and sealing drive structure for up, down, left and right sides, abnormal braking structure, track structure and internal communication method.

[0044] Figure 1This is a schematic diagram of a single screen door with an upper and lower sealing structure implemented by levers; the top frame of the screen door is provided with a top telescopic plate, and the bottom frame is provided with a bottom telescopic plate. At least the outer parts of the top telescopic plate and the bottom telescopic plate are made of soft rubber material. The top telescopic plate and the bottom telescopic plate are both connected to a vertical telescopic mechanism. The vertical telescopic mechanism is connected to a vertical electric push rod 110 and also includes a vertical thrust and / or pull force sensing mechanism 109. The top sealing structure and the bottom sealing structure adopt basically the same drive structure. The vertical thrust and / or tension sensing mechanism 109 detects the top thrust and / or tension and the bottom thrust and / or tension on the top telescopic plate and the bottom telescopic plate respectively through a sensing principle. When sealing is required, the vertical electric push rod controls the vertical telescopic mechanism to slowly extend the top telescopic plate and the bottom telescopic plate outward until the top thrust and / or tension and the bottom thrust and / or tension reach the preset thrust and / or tension values ​​respectively, and then stops extending outward. When sealing is required, the vertical electric push rod controls the vertical telescopic mechanism to retract the top telescopic plate and the bottom telescopic plate inward until the vertical thrust and / or tension sensing mechanism 109 senses that the thrust and / or tension parameter values ​​have reached the set values. Its feature is that it can prevent excessive retraction from overloading the electric push rod, damaging the electric push rod or shortening its service life. The vertical telescopic mechanism specifically comprises a top lever push rod structure and a bottom lever push rod structure, which are identical. The top lever push rod structure includes a top fulcrum 104 and a top lever 103. The top fulcrum is fixed inside the top frame 106. One end of the top lever 103 is connected to the fixed edge B of the top telescopic plate via a connecting rod 102. The connecting rod 102 is connected to the end of the top lever 103 via a rotating shaft and / or bearing. The other end of the top lever 103 is connected to a top push rod 107 vertically disposed inside the side of the partition screen. The top push rod is connected to a vertical electric push rod 110 via a vertical adapter mechanism. A vertical thrust and / or tension sensing mechanism 109 is disposed on the vertical adapter mechanism. The vertical electric push rod 110 is a micro-motor direct push rod, and the vertical thrust and / or tension sensing mechanism uses a thrust and / or tension sensor. By controlling the vertical electric push rod 110, the push rod 107 can be moved up and down, thereby causing the push rod 103 to rotate, and in turn driving the top telescopic plate fixed to one end of the lever to move inward or outward. When the screen door moves to the preset position, the top of the screen door is equipped with roller hangers A1 and A2. The power supply line of the internal circuit system B1 is connected to the power supply point set at the fixed position at the top through the roller hangers A1 and / or A2 to realize power supply. The upper and lower sealing actions can be performed automatically after the power is turned on, or the sealing operation can be triggered by a button or other means.

[0045] When the screen door moves into position and triggers the sealing operation, the automatic control vertical electric push rod 110 pulls the top push rod 107 downwards, corresponding to the bottom sealing by pulling the bottom push rod upwards. The lever 103 rotates clockwise, pushing the top telescopic plate upwards. When the top telescopic plate touches the top surface, it presses upwards against the top surface, and the downward pulling force of the corresponding vertical electric push rod 110 also increases. Thus, the magnitude of the upward pushing and / or pulling force of the top telescopic plate can be obtained by detecting the pulling force of the vertical pushing and / or pulling force sensing mechanism 109. The top anti-thrust threshold value is preset according to the required sealing degree. The pulling force of the vertical pushing and / or pulling force sensing mechanism 109 is monitored. When the pulling force of the vertical pushing and / or pulling force sensing mechanism 109 reaches or exceeds the preset top anti-thrust threshold value, the vertical electric push rod 110 is immediately controlled to stop working, meaning that the current screen has reached the preset sealing degree. Because the extension is automatically controlled by monitoring the thrust and / or pull at the top, rather than by a fixed control, the system automatically achieves the required seal based on different horizontal conditions. The bottom seal operates on the same principle. If this structure requires sealing on the sides, a side seal with the same structure can be added.

[0046] In practical applications, it is often required that more than one screen door is required to form a screen application. Therefore, in order to enable necessary communication or linkage between multiple screen doors, or to share power supply, a cascaded incoming component C1 can be provided on one side of the screen door, and a cascaded outgoing component C2 can be provided on the other side. The cascaded incoming component C1 and the cascaded outgoing component C2 are equipped with multiple flexible terminals.

[0047] Actual screen doors are generally rectangular in shape, with the sides typically longer. To ensure a more even seal on the sides, an alternative drive structure is often used. Figure 2 This is a schematic diagram of a single screen door that includes both a side sealing structure and a bottom sealing structure. Figure 3This is a schematic diagram of a single screen door that includes both side sealing and top and bottom sealing structures; it is generally used in scenarios where there is no light. To focus on explaining the side sealing structure, other components are omitted in this diagram, which only shows the main structural diagrams related to the side sealing structure. The side telescopic mechanism is specifically composed of two symmetrically arranged triangular lever push rod structures. The triangular lever push rod structure includes a triangular rotating component D, which has a triangular fixed fulcrum D2, a triangular pushing rotation point D1, and a triangular driving rotation point D3 at its three corners. The triangular fixed fulcrum D2 is fixed inside the side of the screen door. The triangular pushing rotation point D1 is connected to the fixed edge 201 of the side telescopic plate 202 through a transition rod 203. The triangular driving rotation point D3 is connected to the side electric push rod 205 through a side transition mechanism. The side transition mechanism includes a vertically arranged side rod and a side thrust and / or pull force sensing mechanism 206. To prevent excessively rapid or abrupt lateral extension or retraction, the screen door incorporates a rotating support frame on its inner side. This frame includes a support rod 204, one end of which is rotatably fixed to the side of the screen door. A triangular fixed support point D2 is rotatably fixed to the support rod 204. The support rod 204 also has two or more speed adjustment holes 207. Each of the two side support rods is connected to a speed adjustment hole 207 via a hook 209 equipped with a spring 208. Adjustment can be achieved by adjusting the spring's stiffness coefficient. Furthermore, if a spring is selected, different speed adjustment holes 207 can be used to achieve the desired adjustment.

[0048] The specific working principle is as follows: Due to the long length of the side telescopic plate, single-point control cannot achieve uniform extension and retraction. Therefore, they are installed in pairs. Taking one side as an example, when the screen door moves into place and the user triggers or the seal is automatically triggered, the control side electric push rod 205 extends outward, causing the triangular push rotation point D1 to rotate counterclockwise, driving the side telescopic plate 202 to extend outward. The side telescopic plate 202 extends and presses against the adjacent screen door or column. As the extension and retraction amount changes, the side sealing thrust and / or tension also change. This change is transmitted to the side thrust and / or tension sensing mechanism 206 through the triangular lever push rod, thus achieving the purpose of monitoring the side sealing thrust and / or tension by monitoring the tension of the side electric push rod 205. By pre-setting the pressure relief threshold, different pressure relief thresholds can be set according to different application requirements. When the seal needs to be released, it can also be done automatically. The automatic control side electric push rod 205 is pulled inward, causing the triangular push rotation point D1 to rotate clockwise, which drives the side telescopic plate 202 to retract inward until the tension parameter value of the push and / or tension sensor reaches the set value (its feature is that it can prevent excessive retraction from overloading the electric push rod, damaging the electric push rod or shortening its service life).

[0049] Figure 4This is a schematic diagram of a single screen door that increases the light-transmitting area while incorporating side and top / bottom sealing structures. This embodiment shows a screen door with both side and top / bottom sealing structures. The top / bottom sealing structure, i.e., the vertical telescopic mechanism, uses a simplified direct-push structure, which is simpler than the lever method. Specifically, the vertical telescopic mechanism consists of a top straight push rod structure and a bottom straight push rod structure, located in the middle or on one side of the screen door. The top and bottom straight push rod structures are identical. The top straight push rod structure includes a top straight push rod 111, one end of which is connected to the fixed edge of the top telescopic plate, and the other end of which is connected to a vertical electric push rod 110 via a vertical adapter mechanism. The top straight push rod is vertically positioned, and a vertical thrust and / or pull sensing mechanism is mounted on the vertical adapter mechanism.

[0050] Figure 5 This is a schematic diagram of a cascaded screen door system. Each screen door is equipped with two rail-top electrical connectors. Taking four screen doors (M1, M2, M3, M4) as an example, each of the four screen doors is suspended from the track L by its own two roller hangers. A column P is located below one end of the track L where partitioning is required. Each screen door has a cascaded inlet assembly C1 on one side and a cascaded outlet assembly C2 on the other side. Both the inlet and outlet assemblies C1 and C2 have multiple flexible terminals. All four screen doors are pushed towards the column and tightly connected. Because the flexible terminals of the inlet and outlet assemblies C1 and C2 on each screen door are in contact with each other and slightly compressed, a reliable electrical connection is achieved. The inlet assembly C1 closest to column P is connected to the power terminal on column P. Since the frames of the screen doors are fixed, only the fit design between the frames needs to be ensured to achieve sufficiently small gaps and adequate airtightness. However, due to the uncertainty of the sealing surface on the other side, an automatic side extension mechanism can be incorporated to guarantee a tight seal on that side. Other screen doors do not require this mechanism. The thrust of the screen door with the automatic side extension mechanism compresses its adjacent screen doors, one after another, thus completely sealing the side gaps between all screen doors. As a linkage mechanism, once the last screen door is moved into place, all screen doors with automatic extension mechanisms (top, bottom, left, right) can automatically extend outwards until a preset thrust and / or pull threshold is reached, achieving the desired level of sealing. When the outermost screen door is moved away, it indicates that the seal needs to be removed entirely. The automatic control system will automatically reposition all telescopic mechanisms inward, releasing the sealed partition. Users can then easily move the screen door, even with one hand, to any position on the track.

[0051] In the event of a circuit failure or power outage, the electric push rod will malfunction, thus limiting its practical application and increasing the risk of accidents. To address this issue, a manual reset mechanism is provided on both the top and side telescopic mechanisms. A top telescopic plate is located on the top frame of the screen door, and a bottom telescopic plate is located on the bottom frame. Both the top and bottom telescopic plates are connected to a vertical telescopic mechanism, which is connected to a vertical electric push rod. The vertical electric push rod controls the extension and retraction of the top and bottom telescopic plates through this mechanism. A manual reset mechanism is also provided on the vertical telescopic mechanism, allowing the top and bottom telescopic plates to immediately return to their original positions within the screen door.

[0052] Figure 13 This is a partial structural diagram of the emergency braking mechanism of a vertical telescopic partition screen. The vertical telescopic mechanism specifically comprises a top lever push rod structure and a bottom lever push rod structure, which are identical. The top lever push rod structure includes a top fulcrum and a top lever. The top fulcrum 104 is fixed to the inner side of the top frame. One end of the top lever 103 is connected to the fixed edge of the top telescopic plate, and the other end is connected to a top push rod 107 vertically positioned on the side of the partition screen. One end of the top push rod has a cylindrical push hole 114 with an open end face. A vertical thrust and / or tension sensing mechanism 109 has a push rod 108 facing the top surface. The inner diameter of the push hole 114 is larger than the diameter of the push rod 108. The push rod has an inner braking through hole 115, and each push rod has an outer braking through hole 116. The inner height of the push hole 114 is greater than the length of the push rod. Screw 113 passes through the outer brake through hole and the inner brake through hole to lock the push rod, at least part of the push rod is not inserted into the push hole; the other side of the vertical thrust and / or pull force sensing mechanism 109 is connected to the vertical electric push rod 110; when the brake screw is unscrewed and disengaged from the outer brake through hole and the inner brake through hole, the push rod is fully inserted into the push hole; a brake suspension nut 117 is welded to one side of the outer brake through hole, the brake screw is first screwed into the brake suspension nut and then passes through the inner brake through hole and the outer brake through hole, so that there is still a certain amount of space in the push hole 114. When the vertical electric push rod 110 is driven to push upward or pull downward, it drives the top lever 103 to rotate; when an abnormality occurs, the electric system malfunctions and the screen door needs to be moved urgently, the brake screw is unscrewed and disengaged from the outer brake through hole and the inner brake through hole, but at this time the brake screw is still connected to the brake suspension nut 117 and will not fall off. Due to its own gravity, the top telescopic panel automatically retracts into the screen door, releasing the seal and allowing the screen door to move freely on the guide rail, achieving the purpose of quickly removing the partition.

[0053] The specific working principle is as follows: Due to the long length of the side telescopic plate, single-point control cannot achieve uniform extension and retraction. Therefore, they are installed in pairs. Taking one side as an example, when the screen door is moved into place and the user triggers or automatically triggers the seal, the control side electric push rod 205 extends outward, causing the triangular push rotation point D1 to rotate counterclockwise, driving the side telescopic plate 202 to extend outward. The extended side telescopic plate 202 presses against the adjacent screen door or column. As the extension and retraction amount changes, the side sealing thrust and / or tension also change. This is transmitted to the side thrust and / or tension sensing mechanism 206 through the triangular lever push rod, thus achieving the purpose of monitoring the side sealing thrust and / or tension by monitoring the tension of the side electric push rod 205. By pre-setting the pressure relief threshold, different pressure relief thresholds can be set according to different application requirements. When it is necessary to release the seal, it can also be achieved automatically. The automatic control side electric push rod 205 pulls inward, causing the triangular push rotation point D1 to rotate clockwise, driving the side telescopic plate 202 to retract inward. The vertical telescopic mechanism specifically comprises a top lever push rod structure and a bottom lever push rod structure, which are identical. The top lever push rod structure includes a top fulcrum and a top lever. The top fulcrum 104 is fixed to the inner side of the top frame. One end of the top lever 103 is connected to the fixed edge of the top telescopic plate, and the other end of the top lever is connected to a top push rod 107 vertically positioned on the side of the partition screen. One end of the top push rod has a cylindrical push hole 114 with an open end face. A vertical thrust and / or tension sensing mechanism 109 has a push rod 108 facing the top surface. The inner diameter of the push hole 114 is larger than the diameter of the push rod 108. The push rod has an inner braking through hole 115, and each push rod has an outer braking through hole 116. The inner height of the push hole 114 is greater than the length of the push rod. The brake screw 113 passes through the outer braking through hole and the inner braking through hole to lock the push rod. At least part of the push rod is not inserted into the partition screen. Inside the push hole; the vertical thrust and / or pull force sensing mechanism 109 is connected to the vertical electric push rod 110 on the other side; when the brake screw is unscrewed and disengaged from the outer brake through hole and the inner brake through hole, the push rod is fully inserted into the push hole; a brake suspension nut 117 is welded to one side of the outer brake through hole, and the brake screw is first screwed into the brake suspension nut and then passes through the inner brake through hole and the outer brake through hole, so that there is still a certain amount of space in the push hole 114. When the vertical electric push rod 110 is driven to push upward or pull downward, it drives the top lever 103 to rotate; when an abnormality occurs, the electric system malfunctions, and it is necessary to move the screen door urgently, the brake screw is unscrewed and disengaged from the outer brake through hole and the inner brake through hole (but at this time the brake screw is still connected to the brake suspension nut 117 and will not fall off). Due to its own gravity, the top telescopic plate automatically retracts into the screen door, releases the seal, and allows the screen door to move freely on the guide rail, so as to achieve the purpose of quickly removing the partition.

[0054] Figure 14This is a structural diagram of an emergency braking system for a vertically mounted telescopic partition screen with side sealing. This diagram is a schematic representation of the side telescopic mechanism of a single screen door, including the side sealing structure. Figure 4 A partial structural diagram; details omitted for clarity and emphasis. Figure 4 The other components are shown only in the main structural diagrams related to emergency braking. Specifically, the side-sealing emergency braking mechanism consists of a fixed fulcrum rod 1406 fixed inside the side of the screen door. A brake screw 1409 passes through the elongated holes S1 and S2 of two relatively sliding adapter rods 1405 and 1408, and is engaged with a lock nut. The lock is tightened to allow both adapter rods 1405 and 1408 to slide smoothly. A fulcrum fixing screw 1403 then fixes both adapter rods 1405 and 1408 to the fixed fulcrum rod 1406. The other ends of adapter rods 1405 and 1408 are connected to the top lever push rod structure 1412 and the bottom lever push rod structure 1413, respectively. In case of an abnormality, such as an malfunction in the electric system requiring emergency movement of the screen door, the brake screw 1403 is unscrewed and disengaged from the brake through hole of 1405 and the outer... Braking through hole; however, at this time, the brake screw is still connected to the brake suspension nut on the fixed fulcrum rod 1406 and will not fall off. Due to the gravity of the top lever push rod structure 1410, it automatically retracts into the screen door, causing the side telescopic plate to also retract into the screen door, releasing the side seal. Then, the brake screw 1404 is unscrewed and disengaged from the brake through hole of 1401 and the outer brake through hole of 1402. However, at this time, the brake screw is still connected to the brake suspension nut on 1402 and will not fall off. Due to the gravity of the top lever push rod structure 1410, it automatically retracts into the screen door, causing the top telescopic plate to also retract into the screen door, releasing the side seal (this is the same as the emergency braking principle of the vertical telescopic partition screen described in the previous paragraph), allowing the screen door to move freely on the guide rail, achieving the purpose of quickly releasing the partition.

[0055] To facilitate the movement of screen doors and ensure reliable power supply, especially in applications where side power supply via pillars is not feasible, a top-powered structure via a track is specially designed. Specifically, at least two track-top electrical connectors are installed at the top of the track, each with a top-power connection post connected to a primary power source. Each screen door has one or two roller feet at its top equipped with a corresponding number of screen-top electrical connectors, each with a top-power contact point. The power line of the circuit board on the screen door is electrically connected to this contact point. When the screen door slides into position on the track, its top-power contact point is electrically connected to the top-power connection post, allowing for cascading power supply to other screen doors. Alternatively, the top of the track can have the same number (or more) of track-top electrical connectors as the number of screen doors. When each screen door slides into position on the track, its top-power contact point is electrically connected to the top-power connection post, allowing for individual fixing.

[0056] To further enhance power supply reliability, a set of side column electrical connectors can be installed on the column. Each side column electrical connector has two side electrical connection posts, which are connected to a second power supply. A screen side electrical connector is also provided on the side of the screen door that matches the column. This screen side electrical connector has two side electrical connection contacts, which are matched with the side electrical connection posts. The power lines of the low-voltage power supply lines on the circuit board of the screen door are electrically connected to the two side electrical connection contacts. When the screen door slides into position on the track, the side electrical connection contacts of the screen door are electrically connected to the side electrical connection posts.

[0057] Figure 15 This is a schematic diagram showing the placement of the top electrical connector, rollers, and hollow hanging wheel screws. Because the screen door needs to move dynamically, to achieve electrical connection with the top electrical connector contact point, hollow hanging wheel screws F1 are used to fix the screen door to the hollow movable hanging wheel F2. The movable hanging wheel F2 fits into the rail, suspending the screen door on the rail. A top electrical connector for the screen door is located on the rail. The top electrical connector includes a top electrical connector contact point formed by a top metal elastic connecting post with an inward travel. The positive and ground wires of the power supply line of the circuit board on the screen door pass through the hollow hanging wheel screws on two rollers respectively and are electrically connected to the top electrical connector contact point, or one of the hollow hanging wheel screws on a roller is electrically connected to the top electrical connector contact point. The rail-mounted top electrical connector includes a top electrical connector post C1 formed by a top metal elastic connecting post with an inward travel. The top electrical connector post is connected to the connection line port C2 through an elastic component and is mounted together on the insulating terminal block C3. The screen's top electrical connector includes a top electrical contact point C4 formed by a top metal elastic connecting post with an inward travel. The top electrical contact point C4 can also be an elastic spring. The surface of the top electrical connecting post is a gradually curved surface or a partially flat surface, and the top electrical contact point is cylindrical. Any edge of the top electrical connecting post surface is larger than the diameter of the top electrical contact point. A side input connector is located on the left side of the screen door, and a side output connector is located on the right side. Both the side input and side output connectors include at least two power line contacts, which are matched and configured. Both power line contacts of the side input and side output connectors are contacts with internal elastic components; alternatively, conductive elastic copper sheets can be used to replace the top electrical connecting post and / or the top electrical contact point.

[0058] Figure 16 This is a three-dimensional exploded diagram of the rail-top electrical connector and the hollow hanging wheel screw; Figure 17This is a schematic diagram showing the contact state between the hollow hanging wheel screw and the top electrical connector. The following details the specific structure of the bottom rail top electrical connector and the hollow hanging wheel screw. The top electrical connector mainly includes an upper fixing plate 1001, an upper insulating partition 1002, an insulating protective cover 1003, an insulating fixing main seat 1005, a conductive sheet 1006, a wire connecting ear 1004, a conductive spring 1007, an insulating end plate 1008, a hollow rivet 1009, and several fastening screws. The top electrical connector is installed on the rail, and its purpose is to introduce power from the top. The upper fixing plate 1001 has several through holes. The upper insulating partition 1002 is first fastened to the upper fixing plate 1001. The inner side of the insulating fixing main seat 1005 has a groove with wire connection ears. The conductive wire with an insulating outer layer passes through the upper fixing plate and the upper insulating partition and is electrically connected to the wire connection ears. An insulating protective cover is also provided between the wire connection ears and the upper insulating partition. The insulating protective cover must completely cover the fastening screws on the upper insulating partition to prevent leakage through the fastening screws. The insulating fixing main seat is boat-shaped in general, with the middle part, which is the part with the groove, protruding downwards. Conductive plates extending to the lower surface are provided on one or both sides. The conductive plates are electrically connected to the wire connection ears. The conductive spring is matched with the insulating fixing main seat, covering the protruding bottom of the insulating fixing main seat and electrically connected to the conductive plates. The conductive spring contacts feature a centrally curved connecting lug. Insulating end plates can be fixed to the connecting lugs on both sides using hollow rivets, and then secured to the insulating mounting base with fastening screws, resulting in a complete rail-top electrical connector. This allows the power supply cable to enter from the top and connect electrically to the curved conductive spring contacts at both ends of the bottom. The curved ends of the conductive spring contacts, along the direction of the guide rail's movement, facilitate the movement of the screen-top electrical connector.

[0059] The matching screen top electrical connector is mounted on the hollow hanging wheel screw, mainly including the hollow hanging wheel screw 1106, an inner conductive dielectric sheet 1105A, a convex top electrical connection contact 1102, a top contact spring 1103, an inner movable contact 1104, and an insulated screw locking end 1101. The hollow hanging wheel screw 1106 is completely through the middle, with an external thread at one end and an internal thread at the other. The end with the internal thread has a larger inner diameter, forming a cavity for mounting the convex top electrical connection contact 1102. An externally insulated wire 1105, which is electrically connected to the inside of the screen door, passes through the hollow hanging wheel. The screw is electrically connected to the inner conductive dielectric 1105A and is pressed into the cavity after being installed on an insulating plastic base. The convex top electrical connection contact 1102 is a top electrical connection post with a spherical or arc-shaped surface at one end. The other side of the top electrical connection post is connected to the inner movable conductive dielectric 1104 through a flexible wire. The top contact spring 1103 is set between the inner movable conductive dielectric 1104 and the convex top electrical connection contact 1102. The middle of the insulating screw locking end 1101 is provided with a through hole that matches the convex top electrical connection contact 1102. The convex part of the convex top electrical connection contact 1102 can extend freely from the through hole. The convex top electrical contact point is pressed against the end of the hollow hanging wheel screw 1106 by the insulated screw locking end 1101. The entire structure ensures high insulation between the wire and the hollow hanging wheel screw. Due to the restriction of the insulated screw locking end 1101 and the action of the top contact spring 1103, only the middle convex part of the convex top electrical contact point protrudes from the hollow hanging wheel screw. When an external force presses on the convex top electrical contact point, the top contact spring 1103 can be driven to retract inward. The insulated screw locking end 1101 is an insulated screw component made of engineering plastic with high insulation performance and high strength. It has a round hole in the middle and two specially designed blind holes on the insulated screw locking end 1101 to facilitate the installer to lock the insulated screw locking end 1101 in the center of the screw head of the hollow hanging wheel screw. The 1105 is made by stripping the outer insulation layer of the conductive wire, exposing the copper wire, and fixing it together with the inner copper conductive plate 1105A. This is done using soldering, and after cooling, the wires are connected as a single unit. The inner diameter of the central through-hole in the hollow hanging wheel screw is larger than the outer diameter of the conductive wire with the outer insulation layer. Furthermore, during screen production and installation, before the hollow hanging wheel screw is fully adjusted, the conductive wire with the outer insulation layer is not yet tightened. The inner movable conductive plate 1105A and the conductive wire with the outer insulation layer will not rotate with the hollow hanging wheel screw. This special design ensures that when workers adjust the height of the screen using the hollow hanging wheel screw, the inner movable conductive plate and the conductive wire with the outer insulation layer will not be damaged. Basically, the conductive wire is tightened only after the adjustment is complete. Afterward, if the screw needs to be rotated slightly for further adjustment, the inner conductive plate 1105A will slip and will not rotate with the screw.

[0060] The conductive spring sheet features a unique curved surface composed of nearly parallel parabolas. This surface cleverly and fully utilizes the law of action and reaction, producing a novel and practical effect: The conductive spring sheet, made of wear-resistant material, has an inclined plane on each side and a large, suspended arc-shaped plane in the center. This large arc-shaped plane is formed by a plane and the tops of two nearly parallel parabolas on either side being tangent to each other. The other ends of the nearly parallel parabolas are seamlessly and smoothly connected to the tangent circular arc surfaces. The other end is seamlessly and smoothly connected to the inclined plane tangent to it; the special curved surface design of the large arc plane causes the conductive spring to generate a slow gradient change in the direction of the insulating end plate away from the center. Therefore, in addition to slowly increasing the space for elastic movement, it also allows the thrust between the convex top electrical connection contact point and the conductive spring to increase slowly. Therefore, when the contact points of the convex top electrical connection point and the conductive spring are in motion, the impact force when they push against each other can be mitigated, and there will be no violent changes in thrust and / or tension, thus extending the life of the convex top electrical connection contact point and the conductive spring.

[0061] The conductive spring and the convex top electrical connector contact point are brought into close contact by utilizing elastic strain to generate elastic force: When the convex top electrical connector contact point slides towards the center of the conductive spring, since the highest point of the convex top electrical connector contact point is higher than the lowest point of the conductive spring, after the convex top electrical connector contact point and the conductive spring contact point make contact, their contact points will continuously change position as the caster wheel moves. This movement curve is constrained by the surface on the conductive spring contact point, which is composed of nearly parallel parabolas. Therefore, the convex top electrical connector contact point experiences a corresponding displacement. The highest point of the convex top electrical connector contact point; this is the contact point between the convex top electrical connector contact point and the conductive spring contact point; it will then slowly displace towards the insulating fixing base body. This displacement can... This design allows the conductive spring to undergo elastic strain, generating elastic force and simultaneously buffering the impact force when the convex top electrical connector contact point slides in. The elastic displacement of the conductive spring also induces a force in the vertical direction towards the convex top electrical connector contact point, thus compressing the convex top electrical connector contact point. Consequently, the convex top electrical connector contact point undergoes a corresponding displacement along the centerline of the hollow hanging wheel screw. At the same time, the spring at the convex top electrical connector contact point undergoes compression deformation along the centerline of the hollow hanging wheel screw, and the elastic strain of the spring generates elastic force. This results in a mutual pushing force between the convex top electrical connector contact point and the conductive spring, ensuring that the contact points of both can maintain a tight contact during use, guaranteeing continuous circuit continuity.

[0062] Figure 18 This is a schematic diagram showing the contact status of the side input connector and the side output connector; Figure 19This is an exploded 3D diagram of the side input connector and the side output connector. In applications with multiple screen doors, there is also the issue of connecting adjacent screen doors. Therefore, side input connectors and / or side output connectors can be selected according to actual needs. Since the lateral contact points are all vertically touching and do not require lateral relative movement, it is only necessary to ensure that the vertical electrical contact points have a certain elastic travel. The side input connector specifically includes a side-entry insulating housing 2002, a side-entry metal contact 2004, and a side-entry spring 2003. The side-entry insulating housing has two through holes, and multiple contacts can be connected as needed. The side-entry metal contact is a metal post with two diameters. The larger end 2004B is the contact end, and the smaller end 2004A is the connection end. The small end 2004A has a wiring through hole, a spring clip 2001, and a die screw 2004C. The through hole is slightly larger than the diameter of the small end, the diameter of the large end is larger than the diameter of the side-entry spring, and the diameter of the spring clip is larger than the diameter of the through hole. During installation, insert the side-entry spring from the small end into the through hole, overcoming the spring force so that the small end protrudes from the other side of the through hole. Press in the spring retainer, connect the wire to the wiring through hole, and then tighten the Jimi 2004C screw to secure the wire. The side output connector operates on the same principle as the side input connector. After installation, both the side-entry and side-exit metal contacts of the side output and side input connectors protrude outward due to the spring force, while being constrained by the spring retainer. When two adjacent screen doors touch each other, both the side-entry and side-exit metal contacts are subjected to pushing and / or pulling forces, compressing inward against the spring force. The small end does not continue to protrude inward, and the spring action ensures reliable contact between the side-entry and side-exit metal contacts.

[0063] Figure 20This is a schematic diagram of the unsealed state of a set of screen doors. Each screen door is equipped with a corresponding rail-top electrical connector. Because the screen doors need to move dynamically, when each screen door is equipped with a rail-top electrical connector, in order to achieve electrical connection with the top electrical contact point, the unique roller suspension foot of each screen door uses a hollow suspension screw F1 to fix the screen door to the hollow movable suspension wheel F2. The movable suspension wheel F2 fits into the rail, suspending the screen door on the rail. A top electrical connector for the screen door is located on the rail, and the top electrical connector includes a top metal elastic connecting column with an inward retraction stroke. The top electrical connection points are formed, with the top electrical connectors on every two adjacent screen doors connected to the positive and ground wires of the power supply line, respectively. A side input connector is located on the left side of the screen door, and a side output connector is located on the right side. Each side input and output connector contains at least two power line contacts, which are matched and configured. Both power line contacts of the side input and output connectors are internally elastic; alternatively, conductive elastic copper sheets can be used to replace the top electrical connection posts and / or top electrical connection points. The wires connected to the top electrical connection points of each screen door pass through the hollow hanging wheel screws on the roller hangers, and then utilize the matching power line contacts of the input and side output connectors to form a parallel power supply circuit for the screen doors. The positive and ground wires of the circuit board are connected to the positive and ground terminals of the parallel power supply circuit for this screen door, respectively, and are electrically connected to the top electrical connection points on the hollow hanging wheel screws of the roller hangers. Figure 20 The unsealing action of the first and second screen doors on the left is controlled by the control circuit board to start and start synchronously until the action is completed before the second screen door can be moved. This ensures continuous power supply and prevents the first screen door from failing to operate due to the lack of power supply after the second screen door is moved because of the missing electrode connection.

[0064] Figure 6 This is a schematic diagram of a screen door storage unit on a Y-shaped track. Figure 21 This is a schematic diagram of a typical Y-shaped track structure. Figure 22This is a schematic diagram of a Y-shaped track with an internal guide plate at the top of the rail and its connecting components. The improvement lies in the addition of the internal guide plate B102. The purpose is that when the casters turn, they are restricted within the track by the internal guide plate B102, thus allowing them to move along the direction of the internal guide plate B102 during reversal without generating a large rotation angle. This structure restricts the screen door to move only along the direction of the internal guide plate. The characteristic of the Y-shaped track structure is that the main components of the Y-shaped track structure are cut from straight rail material, and then connected by steel connecting components to form the Y-shaped track structure. Since steel has better mechanical strength than aluminum, the strength of the joints of the Y-shaped track is better than that of the original aluminum straight rail section. The track, fixed to the top of the wall, is hollow with a slot on its bottom for suspending and moving the screen door. The track includes a partition working area (LA), a reversing area (LB), and a storage area (LC). The storage area consists of two parallel storage tracks, with the center-to-center distance L1 between the two ends of each track coinciding with the center-to-center distance L2 between the two hanging legs of the screen door. The reversing area is a Y-shaped track, with its two forked ends connected to the two storage edges of the storage area. The other end of the Y-shaped track connects to the partition working area, which is a single straight track. The hollow interiors of the partition working area (LA), reversing area (LB), and storage area (LC) are interconnected. The two forks of the Y-shaped track are specifically a first fork and a second fork. The first fork merges with the second fork via three line segments to form a single track. Each screen door is equipped with a track-top electrical connector on the partition working area, with each set of connectors connected in parallel. Two top electrical connection posts on each connector are connected to a primary power supply. The Y-shaped track transitions to the partition work area at a right angle, a bend, or a grid pattern. In this state, all screen doors are stored on the track storage area LC. Due to space limitations, the screen doors may be stacked at an angle. Therefore, storage can be achieved simply by ensuring that the center-to-center distance L1 between the two ends of the track is the same as the center-to-center distance L2 between the two hanging legs of the screen door to be suspended. When unfolding for use, the screen doors are moved one by one from the storage area LC to the partition work area LA. Figure 7 This is a schematic diagram of the first state of the movable screen door. Move the screen door M4 towards the partition work area LA. When it can no longer be moved horizontally, move one side of the screen door M4 towards the partition work area LA first, and gradually drive the other side to slide towards the partition work area LA as well, which is equivalent to changing the direction. Figure 8 This is a schematic diagram of the second state of the movable screen door. One side of the screen door M4 first enters the partition work area LA and gradually pulls the other side to slide completely into the partition work area LA as well. Figure 9 This is a schematic diagram showing the position of a single movable screen door when it is in place.

[0065] Then move the screen door M4 completely to the preset position. For example... Figure 10This is a diagram showing the status of all movable screen doors in place. Move all the screen doors one by one to the partition work area LA. Figure 11 This is a diagram of the sealed state. When all the screen doors are moved into place, the sealing operation is automatically or manually started from the top, bottom, left and right. All the side telescopic plates and the top telescopic plate extend and are automatically controlled to achieve the sealed state. Figure 12 This is a diagram illustrating the unsealed state. When removal is required, first initiate the unsealing process, which automatically retracts all side and top telescopic panels into the screen door, restoring the freely movable screen door. If repacking is needed, follow the reverse process of unfolding the screen door to retract all screen doors into the storage area LC.

[0066] Each partition work area is equipped with a rail-top electrical connector matching each screen door. Each rail-top electrical connector has two top electrical connection posts, which are connected to a first power supply. The two branches of the Y-shaped track are specifically a first branch and a second branch. The first branch merges with the second branch into a single track via three line segments. A column is installed at either end of the partition section, and each column has a set of side column electrical connectors with two side electrical connection posts, which are connected to a second power supply. The top electrical connection posts have internal springs that retract inward when subjected to external force.

[0067] Since this solution completely eliminates the need for telescopic plate operators and telescopic plate transmission components, it can significantly increase the visible window area and improve the appearance when applied to glass screens. At the same time, it increases the light transmission area, improves the utilization rate of light resources, and conforms to the concept of environmental protection. By employing a Y-shaped track, the screen can easily change direction horizontally with the moving caster system, including right-angle changes, curve changes, and zigzag changes. This allows the screen door to be easily pushed to any set position, even with just one hand. The ingenious new hollow caster screw system features an innovative vertical circuit power supply component, replacing the conventional solid caster screw system. It allows for selective selection of two power supplies, each with a different voltage, simultaneously supplying power in the vertical and lateral directions. The hollow caster screw has a special brush structure at its top, and a conductive elastic copper sheet component is positioned correspondingly within the track. Therefore, power can be reliably obtained vertically to supply the glass movable partition screen door at any set position during its omnidirectional movement. When two screen doors are brought together and energized, the side and top telescopic panels... It will automatically extend and, under set push and / or pull conditions, tighten the sealing strip to achieve a sound insulation effect. When one of two adjacent screens that has been loosened is pushed open, the side and top telescopic panels of the adjacent screen will automatically retract along with the tightened sealing strip under set push and / or pull conditions, allowing the screen to be moved easily. It can be easily operated by an average adult, and even a small person can move it. Due to the application of a vertical power supply system, it can be installed and used in any set position in a site or space without walls or fixed columns. The electric control system completes the automatic extension, retraction, tightening, or loosening of the movable glass partition screen. In case of power outage, circuit failure, or motor failure, the screen door that has been positioned and tightened can be easily moved by simply loosening one screw. There is no safety hazard of the motor being unable to move due to lack of power supply, preventing people from entering and exiting the room in time.Furthermore, after the emergency safety mechanism is used, it can be reset simply by reconnecting the power and tightening the screws. It completely eliminates the need for manual operation of the telescopic panel actuator, replacing it with an electrically operated telescopic structure. The thrust and / or pull forces for tightening and loosening are set once during product manufacturing according to customer requirements, and these forces are independent of the telescopic length. Therefore, there is no need for repeated adjustments of the thrust and / or pull forces or the telescopic length, yet a sufficient sealing effect is achieved. It also solves the problem of inconsistent ground levels: when the ground level of each screen is different, the pre-set thrust and / or pull forces for tightening and loosening can be used. Since the pull force is independent of the telescopic length, it achieves a sealing effect. It automatically adjusts its extension and contraction without requiring adjustments to the pushing and / or pulling force or the length of the extension and contraction each time it is tightened and loosened. The extension and contraction mechanism stops moving only when it reaches the desired position for the pushing and / or pulling force. Therefore, on a microscopic scale, when the sealing plastic strip and mechanical components pass over uneven horizontal or vertical surfaces, they automatically compensate and reach the set force. This perfectly solves the problems of uneven ground level and insufficient verticality of vertical surfaces. Even if the ground level of each screen is different and the vertical surface is not vertical enough, it can tighten and seal well without adjustment, thus preventing gaps and effectively preventing a reduction in sound insulation. Because a push-pull and / or pull force control system is used, at the microscopic level, when the sealing plastic strip and mechanical components encounter uneven surfaces, they will automatically generate a compensation effect due to the preset push-pull force until the set force is reached before stopping the action. This prevents gaps from being not properly sealed and effectively prevents a reduction in sound insulation. Low-voltage power supply is used to power the screen door, and there are multiple power supply systems. Highly safe low-voltage backup batteries or UPS uninterruptible power supplies can be selectively installed in different locations to provide backup power. In the event of a fire or power outage due to natural disasters, the movable partition screen can still be moved normally, easily expanding the escape route and saving time for evacuation of personnel on site.

[0068] In practical applications, having one concealed door in a set of screen doors makes it easier for people to enter and exit. Figure 23This is a schematic diagram of the unsealed state of a screen door structure with a door-within-a-door feature. The screen door structure shown is specifically designed to facilitate the entry and exit of personnel. The diagram is a schematic diagram of an embodiment of the telescopic mechanism of a single screen door, including an upper sealing structure 2501 and a lower sealing structure 2512. To focus on the sealing structure, other components are omitted in this diagram, which only shows the main structural diagrams related to the sealing structure. The telescopic mechanism specifically consists of a top straight push rod structure 2506 and a bottom straight push rod structure 2511, which are connected to an electric push rod 2510 and installed on one side of the screen door. The top and bottom straight push rod structures, also known as vertical telescopic mechanisms, employ a straight push rod structure to drive the lever. The straight push rods are located on both sides of the screen door. The top and bottom straight push rod structures are different. The top straight push rod structure includes a top straight push rod 2506. One end of the top straight push rod is connected to the active end rotation fulcrum P1 of the central lever. The other end of the top straight push rod is connected to the thrust-pull force sensing mechanism 2509 and the vertical electric push rod 2510 through a vertical transition mechanism. The top straight push rod is vertically arranged, and the vertical thrust-pull force sensing mechanism is located on the vertical transition mechanism. To prevent excessively rapid or abrupt vertical extension or retraction, the screen door features a buffer spring telescopic rod 2502 on its upper interior. Adjustment is achieved by adjusting the spring's stiffness coefficient. The central lever mechanism includes a central lever 2504, which has elongated holes for a fulcrum P2, a driving end rotation fulcrum P1, a driven end rotation fulcrum P3, and a driven end rotation fulcrum P4. The fulcrum P2 is connected to a small door positioning pin 2503 vertically inserted into the internal crossbeam of the screen door. One end of the central lever 2504 is the driving end, and the other end is the driven end. The driving end rotation fulcrum P1 drives the central lever 2504 to drive the driven side rotation fulcrum P3, which is connected to the buffer spring telescopic rod 2502 via a transition rod 2505. The other end of the buffer spring telescopic rod is fixed to the top telescopic plate 2501. The fixed edge 2505 is connected; at the same time, the driving end rotation point P1 drives the driven end rotation fulcrum P4 through the middle lever, and the rotation fulcrum P4 is connected to the vertical transfer push rod 2515; the lower end of the vertical support rod 2515 is connected to the fixed edge of the bottom telescopic plate 2512; the bottom straight push rod 2511 is vertically set, the lower end of the bottom straight push rod is connected to the fixed edge of the bottom telescopic plate 2512, and the other end of the bottom straight push rod 2511 is connected to the vertical electric push rod 2510 and the thrust and pull sensing mechanism 2509 through the vertical transfer mechanism; in the figure, 2507 is the sealing door, 2503 is the small door positioning pin, 2508 is the right side soft sealing strip of the sealing door, 2514 is the left side soft sealing strip of the sealing door, 2517 is the top soft sealing strip of the sealing door, 2516 is the bottom soft sealing strip of the sealing door, and 2013 is the sealing door hinge.The thrust and pull sensing mechanism 2509 detects the direction and magnitude of the force on the top and bottom telescopic plates respectively. When sealing is required, the vertical electric push rod controls the vertical telescopic mechanism to retract, which in turn controls the top and bottom telescopic plates to slowly extend outward while the small door positioning pin 2503 rises. This continues until the top thrust and / or pull and the bottom thrust and / or pull reach the preset thrust and / or pull values ​​(note: at this point, the vertical thrust and / or pull sensing mechanism 109 senses the corresponding pull parameter value), at which point the outward extension stops and the small door is positioned. Pin 2503 has risen to the position away from the small door and stopped rising; when it is necessary to release the seal, the vertical electric push rod controls the vertical telescopic mechanism to extend outward, respectively controlling the top telescopic plate and the bottom telescopic plate to retract inward, while the small door positioning pin 2503 descends, until the vertical thrust and / or tension sensing mechanism 109 senses that the thrust and / or tension parameter value reaches the set value. Its feature is that it can prevent excessive retraction from overloading the electric push rod, damaging the electric push rod or shortening its service life; at this time, the small door positioning pin 2503 has been inserted into the positioning hole of the small door. The vertical telescopic mechanism is specifically a vertical electric push rod mechanism that drives the buffer spring telescopic rod 2502 through the central lever, and then drives the top telescopic plate at the top of the buffer spring telescopic rod to move inward or outward; 2018 is the ground pin limiting component, 2519 is the ground pin sliding adjustment fastener, 2520 is the ground pin guide tube, 2521 is the screen door positioning ground pin, and 2522 is the electrical control box with a built-in control circuit board. When the screen door moves to the preset position, roller feet A1 and A2 are provided on the top of the screen door. The power supply line of the internal circuit system B1 is connected to the power supply point set at the fixed position on the top through roller feet A1 and / or A2 to realize power supply (power can also be supplied to the electrical control box 2522). The upper and lower sealing actions can be performed automatically after the power is turned on, or the sealing operation can be triggered by buttons or other means.

[0069] When the screen door is moved into place, the sliding adjustment fastener 2519 of the ground pin is pulled down, causing the screen door positioning ground pin 2521 to insert into the pre-set and matching ground pin hole on the ground to prevent the screen door from shifting. When the sealing operation is triggered, the vertical electric push rod 2510 is automatically controlled to pull the top push rod 2506 down, and the bottom push rod 2511 is pulled up for the corresponding bottom sealing. The middle lever 2504 rotates clockwise, and the top telescopic plate is pushed up. When the top telescopic plate touches the top surface, it presses the top surface upward, and the downward pulling force of the corresponding vertical electric push rod 2510 also increases. In this way, the magnitude of the upward pushing and / or pulling force of the top telescopic plate can be obtained by detecting the pulling force of the push and pull force sensing mechanism 2509. The required sealing level is pre-set at the top thrust threshold. The tension of the thrust-tension sensing mechanism 2509 is monitored. When the tension of the sensing mechanism 2509 reaches or exceeds the pre-set top thrust threshold, the vertical electric push rod 2510 is immediately stopped, indicating that the screen has reached the pre-set sealing level. Because the extension amount is automatically controlled by monitoring the top thrust and / or tension, rather than by a fixed control, the system automatically achieves the required sealing based on different horizontal conditions. The bottom sealing follows the same control principle. If this structure requires side sealing, a side seal with the same structure can be added.

[0070] Figure 24This is a schematic diagram of the roller hanger; AA is a side sectional view, BB is a front sectional view, and CC is a top sectional view. The roller hanger is a novel roller hanger with a special structure. The roller hanger 15-1 mainly includes an anti-rotation insert 15-2, a tension spring 15-3, a locking screw 15-4, a flat plate 15-5, a spring plate 15-6, and a locking nut 15-7. Besides suspending the screen via the hollow screw, the roller hanger innovatively features an anti-rotation insert 15-2. The inner side of the anti-rotation insert 15-2, near the locking screw 15-4, has a narrow parallel elongated slot. Its width is only slightly larger than the distance between opposite sides of the square cross-section of the hollow screw's middle section. The width of this parallel elongated slot gradually widens with small rounded corners further away from the locking screw 15-4, becoming slightly larger than the outer diameter of the hollow screw. In use, the operator first pushes the end of the parallel elongated slot of the anti-rotation insert 15-2 horizontally towards its thread centerline, pushing it to the end and maintaining a tight position. At this point, the screen is... The tension spring 5-3, with its pre-tension, will be stretched, increasing the tension accordingly. Meanwhile, the inner parallel slot of the anti-rotation insert 15-2 will slide to its end. Simultaneously, the center line of the screw on the roller hanger falls at a position where the width of the parallel slot is slightly larger than the outer diameter of the hollow screw. Workers can easily lock the hollow screw into the roller hanger. Once the hollow screw is rotated and locked to the appropriate position, the worker releases the anti-rotation insert 15-2, and the tension of the tension spring 5-3 pulls the anti-rotation insert 15-2 back to its original position. The narrower part of the parallel slot will then lock the square cross-section of the hollow screw in the middle, preventing it from rotating. This prevents changes in the height (or pushing and / or pulling force) of the top electrical contact of the hollow screw on the screen roller hanger. This novel structure provides significant reliability for the power supply safety and stability of the hollow screw's power supply system.
